SHEET-TURNING APPARATUS.

certain new and useful Improvements in Sheet-Turning Apparatus, of which the following is a specification.

This invention relates broadly to workreversing mechanism, and more particularly to an apparatus for overturning metal plates or .sheets prior to each pass through the rolls of a rolling mill.

The primary object of the invention is to provide a simple, durable and comparatively inexpensive device whereby metal sheets and the like are automatically overturned after each pass through the rolls of a mill to permit loose scale and the llke particles to drop from the upper surfaces of such sheets prior to the return pass, thus preventing such particles from being rolled into the sheets.

A further object is to provide a device of the character mentioned which is of the socalled flopper type and which is adapted to operate and handle the sheets without deforming or otherwise injuring the latter.

With these and other objects in View, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 is a transverse section of a plate receiving table embodying my invention, the latter being shown in initial, or plate receiving, position; Fig. 2 is a similar view, showing the invention occupying a position midway between the limits of its plate-reversing movement; Fig. 3 is a similar view showing the device at the limit of its movement opposite that shown in Fig. 1; Fig. 4 is a broken view somewhat similar to Fig. 2, showing a modified form of gearing; Fig. 5 is a view of the table partially in side elevation and partially in longitudinal section; Fig. 6 is a view similar to Fig. 1, showing a modified form of driving mechanism; and Fig. 7 is a section on the line 77, Fig. 6.

Referring to said drawings, in which like designating characters distinguish like parts throughout the several views1 indicates generally a table of that character commonly employed adjacent to the rolls of a Specification of Letters Patent.

rolling mill and-which alternately serves as a feed-table and a receiving-table for the sheets or other work upon which said rolls operate; and 2 indicates the rollers of said table.

Fixed at a suitable point upon a shaft 3 mounted in bearings 4 under said table is one or more rocker-arms 5, each of which is so disposed as to operate between two adjacent rollers 2, as shown in Fig. 5. Said rocker-arm has its upper end projecting but slightly above the level of said rollers and has pivotally connected thereto a plateturning element 6 consisting of a substantially V-shaped body, the pivotal connection being located at the apex or angle, or at thejunction of the oppositely inclined arms 6 of said element.

Pivotally connected to a lug 7 formed on the outer face of each arm 6' is a link 8 which has its opposite ends pivotally connected to one end of a link 9 the opposite end of which is pivoted at a fixed point, as to lugs 10 formed on the edge of the table 1. Said links 8 and 9 are of such length that, when those at one side are disposed in alinement, the element 6 occupies a reclining position, as shown in Figs. 1, 3 and 6, wherein the lowermost arm is disposed in a horizontal position slightly below the level of the rollers 2, while the other arm occupies a position above said level. At the same time, the links 8 and 9 at the opposite side occupy a suspended position, as shown in said figures.

As a sheet or plate 20 emerges from the rolls of the mill, it is received by the rollers 2 of the table and lies between the arms 6 of the plate-turning element or elements employed on said table. Prior to returning such sheet or plate through the rolls, the rocker arm 5 is actuated to swing from one limit of its rocking movement to the other, as from the position shown in Fig. 1 to that shown in Fig. 3, or vice versa, thus to overturn said sheet or plate to permit loose scale and the like carried on the upper face thereof to drop therefrom. Such movement of the rocker-arm acts to carry the angular end of the body 6 therewith, while the links act upon the upper or free ends of the arms 6 to reverse the position of said element, as will be readily understood.

The means for actuating movement of the rocker-arm may be of any appropriate form, a short lever-arm 11 being preferably fixed upon the shaft 3 which carries the rocker-arm and having pivotally connected to its free end a pitman 12 which may be connected to and actuated by a powerdriven piston rod 13, as shown in Fig. 1, or which may be connected to a suitable geardriven crank 14, as shown in Fig. 4.

In the modification illustrated in Figs. 6 and 7 the plate-turning body is mounted upona horizontal slide 15 which is mounted to reciprocate beneath the surface of the table 1, said slide being pivotally connected to one end of a pitman 12 which has its opposite end pivoted to the free end of a rocker-arm 5 which is pivotally mounted, as at 16, below and between the limits of reciprocating movement of a piston rod 13*. An outwardly directed pin 17 carried by said piston rod 13 operates in a slot 18 provided intermediate the ends of said rockerarm 5*.

From the foregoing it will be observed that I provide a device of simple and inexpensive form for effecting the reversal of sheets and the like. It will further be noted that various slight changes in the form and arrangement of some of the parts may be resorted to without departing from the general spirit or scope of the invention as defined in the appended claims.

WVhat is claimed is- 1. The combination with a sheet-receiving table, of a substantially V-shaped body between the members of which sheets deposited on said table are received, a reciprocable member normally supporting said body in a position wherein one of said members lies below the level of said table and the other'above'said level, said reciprocal member being pivotally connected to the angular portion of said body, pivoted links interposed between the members of said body and the opposite sides of said table, and means for reciprocating said reciprocable member.

2. The combination with a sheet-receiving table, of a body having divergently inclined arms between which sheets deposited on'said table are received, a reciprocable member to which said body is pivotally connected, a series of pivoted links connecting said arms to opposite sides of said table, and means for reciprocating said reciprocable member.

3. The combination with a sheet-receiving table, of a body having divergently inclined arms between which sheets deposited on said table are received, means pivotally connected to said body whereby the latter is shifted transversely across the table, and a series of pivoted links connected to each arm whereby said body is caused to rotate on said shifting means during the shifting movement to a reversed position.

4. The combination with a sheet-receiving table, of a body having divergently inclined arms between which sheets deposited on said table are received, a rocker-arm projecting upward, through and operable between the sides of said table, said body being pivotally mounted on said rockerarm, means for swinging said rocker-arm to shift said body across the table, and flexible means interposed between each of the divergently inclined arms and a side of said table whereby said body is caused to rotate to a reversed position during its shifting movement.

5. The combination with a sheet-receiving table, of a body having divergently inclined arms between which sheets deposited on said table are received, means pivotally connected to said body whereby the latter is shifted transversely across the table, and flexible means interposed between said arms and opposite sides of the table whereby said body is caused to rotate on its shifting means to a reversed position with each shifting movement thereof.

In testimony whereof, I :IillX my signature in the presence of two subscribing witnesses.
